FIG. 2 is a block diagram of a network of data processing systems in which various embodiments may be implemented. Data processing environment 200 is a network of data processing systems such as described above with reference to FIG. 1. Software applications may execute on any computer or other type of data processing system in data processing environment 200. Data processing environment 200 includes network 210. Network 210 is the medium used to provide simplex, half duplex and/or full duplex communications links between various devices and computers connected together within data processing environment 200. Network 210 may include connections such as wire, wireless communication links, or fiber optic cables.

Server 220 and client 240 are coupled to network 210 along with storage unit 230. In addition, laptop 250 and facility 280 (such as a home or business) are coupled to network 210 including wirelessly such as through a network router 253. A mobile phone 260 may be coupled to network 210 through a mobile phone tower 262. Data processing systems, such as server 220, client 240, laptop 250, mobile phone 260 and facility 280 contain data and have software applications including software tools executing thereon. Other types of data processing systems such as personal digital assistants (PDAs), smartphones, tablets and netbooks may be coupled to network 210.

Server 220 may include software application 224 and data 226 for managing displayed content based on a predefined policy or other software applications and data in accordance with embodiments described herein. Storage 230 may contain software application 234 and a content source such as data 236 for managing displayed content based on a predefined policy. Other software and content may be stored on storage 230 for sharing among various computer or other data processing devices. Client 240 may include software application 244 and data 246. Laptop 250 and mobile phone 260 may also include software applications 254 and 264 and data 256 and 266. Facility 280 may include software applications 284 and data 286. Other types of data processing systems coupled to network 210 may also include software applications. Software applications could include a web browser, email, or other software application that can manage displayed content based on a predefined policy.

Server 220, storage unit 230, client 240, laptop 250, mobile phone 260, and facility 280 and other data processing devices may couple to network 210 using wired connections, wireless communication protocols, or other suitable data connectivity. Client 240 may be, for example, a personal computer or a network computer.

In the depicted example, server 220 may provide data, such as boot files, operating system images, and applications to client 240 and laptop 250. Server 220 may be a single computer system or a set of multiple computer systems working together to provide services in a client server environment. Client 240 and laptop 250 may be clients to server 220 in this example. Client 240, laptop 250, mobile phone 260 and facility 280 or some combination thereof, may include their own data, boot files, operating system images, and applications. Data processing environment 200 may include additional servers, clients, and other devices that are not shown.

In the depicted example, data processing environment 200 may be the Internet. Network 210 may represent a collection of networks and gateways that use the Transmission Control Protocol/Internet Protocol (TCP/IP) and other protocols to communicate with one another. At the heart of the Internet is a backbone of data communication links between major nodes or host computers, including thousands of commercial, governmental, educational, and other computer systems that route data and messages. Of course, data processing environment 200 also may be implemented as a number of different types of networks, such as for example, an intranet, a local area network (LAN), or a wide area network (WAN). FIG. 2 is intended as an example, and not as an architectural limitation for the different illustrative embodiments.

Among other uses, data processing environment 200 may be used for implementing a client server environment in which the embodiments may be implemented. A client server environment enables software applications and data to be distributed across a network such that an application functions by using the interactivity between a client data processing system and a server data processing system. Data processing environment 200 may also employ a service oriented architecture where interoperable software components distributed across a network may be packaged together as coherent business applications.

FIG. 3 is a block diagram of a data processing system 300 utilizing a privacy management system in accordance with a first embodiment. Data processing system 300 includes a computer system 305 with a persistent memory 310, a processing unit 320, and an I/O interface 330. I/O interface 330 is in communication with various peripherals including display 340, web camera 350, contact sensitive keyboard 360, and contact sensitive mouse 370. Display 340 is used to display content which may be sensitive. Display 340 may be a cathode ray tube (CRT) display, a liquid crystal display (LCD), a light emitting diode (LED) display, a touch sensitive LCD or LED display, etc. Web camera 350 may detect the presence and physical proximity of a user by motion detection, by body or facial recognition, or by other types of detection, including thermal, depending on the capabilities of the web camera and the software available. Web camera 350 may also be used to determine whether the user is looking at display 340 or not using well known techniques. Web camera 350 may be another type of camera or video capture unit. Contact sensitive keyboard 360 and mouse 370 are able to detect when a user is in contact with that peripheral. This may be detected by a pressure exerted by the weight of the user's hand on the keyboard, mouse or laptop casing. Alternative, such contact may be detected by electro-sensitive sensors that detect the galvanic skin response of a user by utilizing two or more contact points on a mouse, keyboard and/or laptop casing. Other forms of contact detection may be utilized in alternative embodiments. Other peripherals with similar capabilities may also be in communication with computer system 305 through I/O interface 330.

Memory 310 includes an operating system 311, policy manager 312, policy database 313, a first application (App1) 315, a second application (App2) 316, a first document (Doc1) 317, and a second document (Doc2) 318. Policy manager 312 implements privacy policies maintained in policy database 313. Policy manager 312 monitors the various peripherals through operating system 311. Based on the user interactions with those peripherals, such as a user breaking contact with a mouse, keyboard or laptop casing, the policy manager may determine that the user has broken contact through the operating system, determine the appropriate action based on the policy database, and then instruct the operating system to hide, minimize, screen save, password prompt, run a script, run a program, etc. windows displaying certain applications or documents. App1 and App2 are applications that may be protected with a privacy policy depending on previously entered information in policy database 313. In addition, Doc1 and Doc2 may be similarly protected with a privacy policy depending on previously entered information in policy database 313.

FIGS. 4A and 4B are block diagrams of a policy database in accordance with the first embodiment. The policy database may be predefined by a user, administrator, or other authorized person. The policy database has two parts, a policy schedule 400 shown in FIG. 4A and a policy selection 450 shown in FIG. 4B. Alternative embodiments may utilize a single database structure or other types of database structures for all the elements shown in FIGS. 4A and 4B.

Policy schedule includes a mode 410, a rank 415, a first actionable event (Event1) 420, a first policy action (Action1) 425, a second actionable event (Event2) 430, a second policy action (Action2) 435, and a status 440. Mode 410 is an environment where the user is located. This may be determined from the network the user is utilizing for communications. The user may also indicate the mode through a user interface. Rank 415 is the level of sensitivity of a system, application, or document. For example, the system may generally be of low sensitivity, an application such as email may be of high sensitivity, and a certain document may be of medium sensitivity. The application of a sensitivity rank is shown in policy selection 450 below. First actionable event 420 is an identifiable event meeting certain predefined criteria which is used to invoke a policy action. Examples include identifying the removal of user contact with a computer peripheral such as the user breaking contact with the keyboard, mouse or laptop casing, the user looking away from the display as detected by a web camera, etc. Different types of contact breaks may be handled differently. First policy action 425 is the action immediately taken for a given mode and rank when an actionable event occurs. Immediately may not be nearly instantaneously, but a short time period such as less than 3 or 5 seconds. This time period may be adjustable by the user or an administrator. The first policy action may be for hiding sensitive displayed information such as by minimizing a window containing the displayed information, hiding the content by displaying a non-sensitive background and locking the system, screen saving, password prompting, etc.

Second actionable event 430 is an identifiable event meeting certain predefined criteria which is used to undue a prior first policy action. Examples include identifying user contact with a computer peripheral such as the user reestablishing contact with the keyboard, mouse or laptop casing, the user looking back at the display as detected by a web camera, the user manually maximizing a window, the user entering a password, etc. More extensive security measures may be utilized such as biometric measurements of the user's face to verify identity. Second policy action 435 is the action taken for a given mode and rank when a second actionable event occurs. The second policy action may be to display the sensitive information such as by maximizing a window or by replacing the non-sensitive background with the previously displayed sensitive information. Status 440 identifies whether the policy manager is awaiting a first actionable event (clear) to perform a first policy action or whether a first actionable event has occurred (posted) and the policy manager is awaiting a second actionable event to perform a second policy action.

As shown in the example provided in FIG. 4A, for low sensitivity items (e.g., windows) in any mode, the system may be locked after the user has broken contact with a laptop casing (contact break 2). This may also be detected by a web camera or other peripheral. User proximity may be reestablished by the user entering a password. For medium sensitivity windows in the work and home modes, those windows may be temporarily minimized or otherwise hidden when user contact is broken with a peripheral such as a mouse and keyboard, but automatically unhidden when contact is reestablished. For medium sensitivity windows in a public mode, those windows may be minimized or otherwise hidden, but user action is needed (e.g., to click on the window icon) to unhide those windows when contact is reestablished. For high sensitivity windows in a work mode, those windows are minimized or otherwise hidden when user contact is removed, such as the user looks away from the display breaking eye contact as detected by a web camera, but unhidden when the user looks back at the display establishing eye contact. For high sensitivity items in a home or public mode, those windows are minimized when the user looks away from the display and user action is needed to unhide those windows when the user looks back at the display. That user action may be to enter a password or to manually unhide (maximize) the high sensitivity windows. These actions are for illustrative purposes only and many other types of actions may be taken.

Policy selection 450 includes a set of application/document windows or other items for which a sensitivity rank has been selected. Not all items (e.g., software applications, documents, etc.) need have a sensitivity selected for those items, just those items with sensitive content such as confidential information. The first column lists the items 460 identified as containing sensitive content and the second column identifies the sensitivity ranking 470 for those items. In the example provided in this embodiment, the system as a whole is given a low sensitivity ranking, App1 and App2 are given a medium sensitivity ranking, Doc1 is given a high sensitivity ranking, and Doc2 is given a low sensitivity ranking. Each item is then treated according to their sensitivity ranking as described in policy schedule 400. For example, if the user looks away from the display in a work environment, Doc1 will be hidden from view while the other less sensitive documents, applications or other elements continue to be displayed until the user looks back at the display. If Doc1 is being displayed within a window by App1, the high sensitivity of Doc1 will override the medium sensitivity of App1.

FIG. 5 is a flow diagram of the operation of the policy manager in accordance with the first embodiment. In a first step 500, the policy manager obtains activity information from the operating system. Such activity can include first actionable events (e.g., user breaks contact, inaction for a period of time) or second actionable events (user looks back at display, user enters password). In a second step 510 the policy manager determines whether a first actionable event (Event1) has occurred meeting the criteria set forth in the predefined policy database. A first actionable event is any event identified in the policy schedule that would invoke a first policy action (Action1). If no first actionable event has occurred, then processing continues to step 530, otherwise processing continues to step 515. In step 515, it is determined whether the status is clear for any event identified in step 510 above. For example with reference to FIG. 4A, if the user has looked away from the display and the status is clear for work high risk, home high risk, or public high risk, then any item marked as high risk may meet this criteria. If yes in step 515, then processing continues to step 520, otherwise processing continues to step 530. In step 520, an Action1 should be performed in response to Event1 for any item which has the matching risk level, mode, and clear status. In example with reference to FIG. 4, if the user has looked away from the display, then any high risk item (Doc1) should have Action1 performed (minimize window) for the given mode with a clear status. Where Action1 is performed, the status should be set to “posted” in step 525. Processing then continues to step 530.

In step 530, it is determined whether a second actionable event (Event2) has occurred meeting the criteria set forth in the predefined policy database. A second actionable event is any event identified in the policy schedule that would invoke a second policy action (Action2). If no second actionable event has occurred, then processing returns to step 500, otherwise processing continues to step 535. In step 535, it is determined whether the status is posted for any event identified in step 530 above. For example with reference to FIG. 4A, if the user has looked back at the display and the status is posted for work high risk, then any item marked as high risk may meet this criteria. If yes in step 535, then processing continues to step 540, otherwise processing returns to step 500. In step 540, an Action2 should be performed in response to Event2 for any item which has the matching risk level, mode, and clear status. In example with reference to FIG. 4, if the user has looked back from the display, then any high risk item (Doc1) should have Action1 performed (minimize window) for the given mode with a posted status. Where Action2 is performed, the status should be reset to “clear” in step 545. Processing then returns to step 500.

FIG. 6 is a block diagram of a server client system 600 utilizing a privacy management system in accordance with a second embodiment. Server client system 600 includes a server 610, client system 640 (Client-A) and client system 670 (Client-B) that communicate with each other across a network 699. Network 699 may be an internal network within an enterprise or the internet. Although this is shown as a server client system, it may also be a cloud implementation or other multi-client or multi-user system.

Server 610 includes a persistent memory 620, a processing unit 630, and an I/O interface 635 in communication with each other. I/O interface 635 is also in communication with Client-A and Client-B through network 699. Memory 620 includes an operating system 622, a policy manager 624, and a master policy database 626. Server 610 may also include I/O elements such as a display, keyboard and mouse for an administrator to utilize. However, an administrator may also utilize a client system for that purpose.

Client-A 640 includes a persistent memory 650, a processing unit 660, and an I/O interface 662 in communication with each other. Memory 650 includes an operating system 652 (OS), a policy manager instance 654, a policy database 656, a first application 658 (App1), and a first document 659 (Doc1). Policy manager instance 654 may be an instance of a policy manager 624 that can be updated when the server policy manager is updated. Alternatively, server 610 may not contain a policy manager and each client may contain a separate policy manager that is administered individually. Policy database 656 may be periodically reconciled with the server master policy database 626. The entries in the client policy database may be a subset of relevant entries derived from the master policy database. I/O interface 662 is also in communication with Client-A and Client-B through network 699. Client 640 may also include various peripherals including a display 665, contact sensitive keyboard 666, contact sensitive mouse 667 and contact detector 668. Contact detector may be a weight sensor within a chair, a contact sensor in a flooring material near the system such as under a desk, a thermal sensor, or other type of sensor which can determine whether the user with in contact with the peripheral.

Client-B 670 includes a persistent memory 680, a processing unit 690, and an I/O interface 692 in communication with each other. Memory 680 includes an operating system 682 (OS), a policy manager instance 684, a policy database 686, a second application 688 (App2), and a second document 689 (Doc2). Policy manager instance 684 may be an instance of a policy manager 624 that can be updated when the server policy manager is updated. Alternatively, server 610 may not contain a policy manager and each client may contain a separate policy manager that is administered individually. Policy database 686 may be periodically reconciled with the server master policy database 626. The entries in the client policy database may be a subset of relevant entries derived from the master policy database. I/O interface 692 is also in communication with Client-A and Client-B through network 699. Client 670 may also include various peripherals including a display 695, contact sensitive keyboard 696, contact sensitive mouse 697, and web camera 698.

Displays 665 and 695 are used to display content which may be sensitive. The displays may be a cathode ray tube (CRT) display, a liquid crystal display (LCD), a light emitting diode (LED) display, a touch sensitive LCD or LED display, etc. Web camera 698 may detect the presence of a user by motion detection, by body or facial recognition, or by other types of detection, including thermal, depending on the capabilities of the web camera and the software available. Web camera 698 may also be used to determine whether the user is looking at a display or not using well known techniques. Web camera 698 may be another type of camera or video capture unit. Each contact sensitive keyboard, mouse and laptop casing is able to detect when a user is in contact with that peripheral. This may be detected by a pressure exerted by the weight of the user's hand on the keyboard, mouse or laptop casing. Alternative, such contact may be detected by electro-sensitive sensors that detect the galvanic skin response of a user by utilizing two or more contact points on a keyboard, mouse and/or laptop casing. Other forms of contact detection may be utilized in alternative embodiments. Other peripherals with similar capabilities may also be in communication with clients 640 and 670 through I/O interfaces 662 and 692.

Policy manager instances 654 and 684 implement privacy policies maintained in policy databases 656 and 686. Each policy manager instance monitors the various peripherals through an operating system. Based on the user interactions with those peripherals, such as a user breaking contact with a keyboard, mouse or laptop casing, the policy manager may determine that the user has broken contact through the operating system, determine the appropriate action based on the policy database, and then instruct the operating system to hide, minimize, etc. windows displaying certain applications or documents. App1 and App2 are applications that may be protected with a privacy policy depending on previously entered information in the policy databases. In addition, Doc1 and Doc2 may be similarly protected with a privacy policy depending on previously entered information in the policy databases.

FIGS. 7A and 7B are block diagrams of a policy database in accordance with the second embodiment. The policy database may be predefined by a user, administrator, or other authorized person. The policy database has two parts, a policy schedule 700 shown in FIG. 7A and a policy selection 750 shown in FIG. 7B. Alternative embodiments may utilize a single database structure or other types of database structures for all the elements shown in FIGS. 7A and 7B. In this example, no mode is utilized as it is assumed that all clients are in a work environment. Alternative embodiments may utilize multiple modes or other categorizations to further delineate security levels and concerns.

Policy schedule 700 includes a client 710, a rank 715, a first actionable event (Event1) 720, a first policy action (Action1) 725, a second actionable event (Event2) 730, and a second policy action (Action2) 735. No status is stored in the policy schedule, but in the policy selection in this embodiment. Client 710 is the client for each entry. In this example, there are two clients, so there are a set of entries for each client. The entries may be modified by the client and/or by an administrator, depending on the configuration. Because Client1 does not have a web camera, no events or actions for Client1 require a web camera. In a local copy of the policy schedule, only the entries may be downloaded for that client for maintaining security over the preferences. Rank 715 is the level of sensitivity of a system, application, or document. For example, the system may generally be of low sensitivity and an application such as email may be of high sensitivity. Only two levels of sensitivity are shown in this embodiment, but additional levels may be utilized in alternative embodiments. The application of a sensitivity rank is shown in policy selection 750 below. First actionable event 720 is an identifiable event which is used to invoke a policy action. Examples include identifying the removal of user contact with the computer peripheral such as the user breaking contact with the keyboard, mouse and laptop casing, the user looking away from the display as detected by a web camera, etc. Different types of contact breaks may be handled differently. First policy action 725 is the action immediately taken for a given mode and rank when an actionable event occurs. Immediately may not be nearly instantaneously, but a short time period such as less than 3 or 5 seconds. This time period may be adjustable by the user or an administrator. The first policy action may be for hiding sensitive displayed information such as by minimizing a window containing the displayed information or by displaying a non-sensitive background and locking the system.

Second actionable event 730 is an identifiable event which is used to undue a prior first policy action. Examples include identifying user contact with a peripheral such as the user reestablishing contact with the keyboard, mouse or laptop casing, the user looking back at the display as detected by a web camera, the user manually maximizing a window, the user entering a password, etc. Second policy action 735 is the action taken for a given mode and rank when a second actionable event occurs. The second policy action may be to display the sensitive information such as by maximizing a window or by replacing the non-sensitive background with the previously displayed sensitive information. A variety of actions are shown for illustrative purposes only and many other types of actions may be taken.

FIG. 7B is a policy selection 750 for Client 1 in this example. A separate policy selection table may be utilized in Client2. A centralized policy selection table may be utilized in an alternative embodiment. Policy selection 750 includes a set of application/document windows or other items for which a sensitivity rank has been selected. Not all items (e.g., software applications, documents, etc.) need have a sensitivity selected for those items, just those items with sensitive content such as confidential information. The first column lists the items 760 identified as containing sensitive content. The second column identifies the sensitivity ranking 770 for those items. The third column identifies the status 780 of a given item. Status 780 identifies whether the policy manager is awaiting a first actionable event (clear) to perform a first policy action or whether a first actionable event has occurred (posted) and the policy manager is awaiting a second actionable event to perform a second policy action.

In the example provided in this embodiment, the system as a whole is given a low sensitivity ranking, App1 is given a low sensitivity ranking, and Doc1 is given a high sensitivity ranking. Each item is then treated according to their sensitivity ranking as described in policy schedule 400.

FIG. 8 is a flow diagram of the operation of the policy manager in a first client in accordance with the second embodiment. In a first step 800, Client1 downloads the appropriate portions of the policy database. In a second step 805, Client1 downloads and invokes an instance of the policy manager. Alternatively, Client1 may retain a prior copy of the policy database and policy manager and just download updates. In step 810, the policy manager then obtains activity information from the operating system. Such activity can include first actionable events (e.g., user breaks contact, etc.) or second actionable events (user looks back at display, user enters password). Then in step 815 the policy manager determines whether a first actionable event (Event1) has occurred meeting the criteria set forth in the predefined policy database. A first actionable event is any event identified in the policy schedule that would invoke a first policy action (Action1). If no first actionable event has occurred, then processing continues to step 840, otherwise processing continues to step 820. In step 820, any items with the same rank as the event are then identified. In step 825, it is determined whether the status is clear for any item identified in step 820. For example with reference to FIG. 7A, if the user has broken contact with the keyboard, mouse and laptop casing, then the rank is low. The items with a low rank are the system and Appl. Since the status of App1 is posted, then only the system would meet this criterion. If yes in step 825, then processing continues to step 830, otherwise processing continues to step 840. In step 830, an Action1 should be performed in response to Event1 for any item which has the matching risk level and clear status, which is the system in this example. For the items where Action1 is performed, the status should be set to “posted” in step 835. Processing then continues to step 840.

In step 840, it is determined whether a second actionable event (Event2) has occurred meeting the criteria set forth in the predefined policy database. A second actionable event is any event identified in the policy schedule that would invoke a second policy action (Action2). If no second actionable event has occurred, then processing returns to step 810, otherwise processing continues to step 845. In step 845, any items with the same rank as the event are then identified. In step 850, it is determined whether the status is posted for any item identified in step 845. For example with reference to FIG. 4A, if the user has reestablished contact with the keyboard, mouse or laptop casing, then any item marked as low risk may meet this criterion. The items with a low rank are the system and App1. Since the status of App1 is posted, then only App1 would meet this criterion. If yes in step 850, then processing continues to step 855, otherwise processing returns to step 810. In step 855, an Action2 should be performed in response to Event2 for any item which has the matching risk level and posted status. Where Action2 is performed, the status should be reset to “clear” in step 860. Processing then returns to step 810.

FIG. 9 is a diagram of a user interface 900 for establishing a policy database entry in which various embodiments may be implemented. A user can use a pull-down menu to select an item 910 and client 920 for which this action applies. Item 910 may be an application, a document, etc. If a user is only available to update the security for a single client, then choice 920 may not be provided. The user is also given a choice 930 to add a new entry, update an existing entry, of delete a prior entry into the policy database. The user can then select a mode 940 and rank 945 for the database entry. Other choices can be made available depending on the system configuration. The user can then select an Event1 950 and a resulting Action1 955. The user also selects an Event2 960 and a resulting Action2 965 to counter the effects of Action1. Once the user has completed this screen, the user can then press an Apply button 970 to perform the desired changes to the policy database.
